Application filed April 10, 1916. Serial No. 90,143.

To all whom it may concern:

Be it known that I, JOSEPH P. MAY, a subject of the Emperor of Germany, (having taken out his first papers as a citizen of the United States,) residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Radiators, of which the following is a specification.

My invention relates to radiators and its object is to provide a construction adapted to obtain a tortuous passage of the water therethrough so as to thereby effectually cool the water, to provide a construction the units of which may be readily assembled and which will afford large radiating surface relatively to the volume of water passing through the channels inclosed by said surface and to generally improve the construction of a radiator for automobiles.

With the above objects in view, my invention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated in the accompanying drawings. In this construction, Figure 1 is a front view in elevation of partof a radiator showing my invention in one form thereof applied thereto; Fig. 2, an enlarged.

detail vertical section of part of the radiator core in one form thereof; Fig. 3, an enlarged vertical section of one of the radiator units; Fig. 4, a similar view of another radiator unit adapted to be employed in connection with the member shown in Fig. 3; Fig. 5, a vertical section of a radiator element adapted to be employed if desired in connection with the units shown in Figs. 3 and 4; Fig. 6, a vertical section of part of a core showing all three of the units illustrated in Figs. 3, 4 and 5, assembled in the same core; Fig. 7, a detail perspective view of the unit illustrated in Fig. 4, and Fig. 8, a detail perspective view of the unit shown in Fig. 5.

Referring to the drawings, 1 denotes a radiator casing and 2 a water receiving chamber in the upper part of said casing. A plate 3 of thin metal having flat plane vertical faces and hollow fins 4, extending from one of said faces, constitutes the rincipal unit of my construction. This p ate is shown separately in Fig. 3. The hollow finsconstitute horizontal water channels into which the water from the vertical spaces between two adjacent units, is led.

- Adapted to cotiperate with the unit 3 in the assembled core is a plate unit 5,'sepa- Patented Feb. 19, 1918.

rately shown in Figs. 4 and 7 and having fiat vertical plane faces adapted to be opposed to and spaced from the corresponding faces of the units 3 to provide vertical water channels. This spacing is effected by means of raised inwardly projecting shoulders or flanges 6 extending alon the vertical side borders of the plate an adapted to bear against similar formations on the plates 3, whereby the adjoining plates are spaced apart centrally and lie flat against one an other at their ends, thereby closing the core at such ends.

The plate unit 5 is provided with hollow water channel fins 7 extending at right angles from one face of the plate and with flat closed or solid flow interrupting horizontal fins extending from the opposite face and located between the hollow fins. The units 3 and 5 are adapted when assembled to be so positioned that their respective channel fins 4 and 7 extend in opposite directions as indicated in Figs. 2, 3 and 4. The fins 8 of the unit 5. are adapted to project into opposing hollow fins 4 of the plate unit 3 to constitute water interrupting and diverting means, adapted to deflect the downward currents of water, and cause them to flow outwardly horizontally to the ends of the transverse channels over the solid fins and then back again under the same to the next vertical water space thus compelling a slow passage of the water through a circuitous channel having a. wide area of surface radiation relative to the volume of water passing through the channels.

The interfitting of the fins 4 and 8 also serves to retain the plates in position, renderin unnecessary any securing means therefor other than solder applied to the opposite ends of the adjoined plates. Such formation of the plates also enables them to be readily assembled.

The upper ends of the spaced plates provide open entrance tubes 9 into which the water from the chamber 2 enters.

In Fig. 2, a core is shown composed of units 3 and 5, and in this the first unit at each side is a plate 3. Taking the left hand side, the next unit is a plate 5, then another plate 5 follows, reversed so as to have its respective fins project in opposite directions to those of the first of the units 5. Then follows another unit 3 with its fins projecting to the right, then a unit 5, and the latter alternate arrangement is continued to the other side of the radiator.

In Figs. 5 and 8, a form of plate unit 10 is shown, which is adapted to be used in conjunction with the plates 3 and 5 to form a core, like that illustrated in Fig. 6, when it is desired to provide a core having less water circulating space. This plate has closed or solid fins l1 projecting alternately from opposite faces of the plate and adapted to contact with the two adjoining plates 3 and 5 on opposite sides of the plate 10. In

the assembly shown in Fig. 6, every third unit is of the form shown in Figs. 5 and 8.

The water enters the open tubes at the top of the core and flows down the vertical channels and is diverted into the horizontal, constricted channels by means of the interrupting and diverting fins wherever such .occur, and will also enter the unrestricted "side channels. This mode of passage of the Water insures a slow travel of the same over relatively wide radiating areas, thus efi'ectually cooling the water before it reaches the bottom.

Cross reference is hereby made to appli cation filed by me, Serial No. 90,142.

Having thus described my invention what I claim'is:

l. A radiator having a unit consisting of a metal plate having hollow channel fin's only, said fins extending from one face thereof and a unit having solid closed fins adapted to enter opposing hollow fins in the first unit to provide water interrupting and diverting means.

2. A radiator construction comprising a pair of plate units adapted to be placed together face to face and having means for spacing them apart centrally to provide vertical Water spaces between them, one of said plate units being provided on one side thereof with horizontal hollow water channel fins only and the other plate unit being provided with solid closed flat water-interrupting fins in the face thereof adjacent to said firstplate and adapted to enter hollow fins on the first plate, said second plate being also prohorizontal fins projecting from one face thereof alternately between the location of the hollow fins on the other unit, and said second unit having solid closed water-interrupting horizontal fins projecting from its opposite face, and adapted to register with and enter opposite hollow fins 1n the first unit.

4. A radiator having a series of plate units provided with hollow horizontal fins,

the fins of adjacent units of said construction being respectively staggered vertically, in combination with a plate-unit having oppositely projecting solid closed fins only, said fins extending from opposite sides thereof alternately, said solid fin plate units being mounted between the adjoining hollow fin plate units and spacing the latter apart.

5. A radiator comprising plate units having hollow fins only, said fins projecting from one face thereof substantially at right angles thereto, plate units adapted to be placed adjacent ing flat closed solid water-interrupting fins on one face thereof registered with and entering the hollow fins of said first units, said second units also having hollow fins projecting from its opposite face intermediate said solid closed fins, and a third set of plate units having staggered solid closed horizontal fins on each face thereof, said last named plate units bein disposed in the radiator core between ad acent plates of the first two respective sets and adapted to project against the flat faces thereof.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 7th day of April, A. D.- nineteen hundred and sixteen.
